REI Airflyte Tight
Here's what other sites are saying:
These REI Airflyte tights offer a high-performance layer for kids to wear under their cold-weather clothing. Super stretchy polyester/spandex blend, elastic waist and gusseted crotch offer comfortable fit and unrestricted range of movement. Fabric provides UPF 50+ sun protection, shielding skin from harmful ultraviolet rays. The REI Airflyte tights feature an athletic cut that hugs close to the body, yet offers a more relaxed fit than adult activewear.
